OF 1 V0UNT CLEMENS, MICHIGAN OILING DEVICE 'FOR AUTOMOBILES Application filed December This invention relates to improvements in oiling devices, more particularly for use in connection with automobiles and has for its object the oiling of such parts of the chassis of an automobile that are usually'greased or 1 oiled by hand at stated intervals.

A further object of my invention is, to make 7 the greasing of the chassis entirely automatic and independent of the operator, I 7

Another object of this invention is to make 10 thesupply of oil tothe difierent parts ofthe chassis positive in action by supplying oil under forced feed to each individual bearing, thereby eliminating the possibllity' of clogging as it so often happens in grouplubrication. 1 o v Another object ofmy invention isthe 'possi-' bility of regulating the oil supply to the different bearings according tofthe needs of the chassis on smooth and ro'ugh roads, or inne w and old machinesQ y r In the 'drawings: j

Referring now to the drawings, numeral 1 representsa circular housingymade of brass or bronze which is formed at'its'right hand upperportion Fig. 1, intoa plunger barrel 2 threaded at its upper end. A tempered steel 4 plunger 3 isadapted to move in a vertical direction" in plunger barrel 2, and is pointed at its lower end and cut out at "its left side to provide an unobstructedadmission .ofoil at any position of the plunger through intake 50 40f housing 1. 'A spring (not shown) and'an lease valve spring 34.

vents 35 are also provided in lower dia 5, 1928. Serial No. 323,971.

intake valve ball 5 are adapted to shutoff the flow of 011 when theplunger is on the downward stroke. A housing core 6 is placed in the center of the housing adjacent toball 1 retainer plates which in turn lie in contact with outsideplates 16 the whole being fastened by means of tie screws 15 to housing 1 thereby forming a runway 7 of square cross section in which a key ball 11 and smaller idler balls 12 Fig. 1, are afforded'freemoyechassis. Each discharge port 8 is equipped Wl-thfl discharge port'ball 9 actuated by a discharge port ball spring 10. Discharge port ball 9 extends'slightly into the runway 7 Fig. 3, through a hole provided in ball retainer plate 4c5wwhen the vent is closed. .1 By varying the depth to which these discharge port balls extend into the runway I can permanently regulate the supplyof oil fed through the oil ng, for release spring23 while'diaphragmj lock nut 18v provides the corresponding lower seat forspring 23.

lines and increase or decrease the amount of 'm'ent in a clockwise direction. The outside is connected to a diaphragm ring 21 which in turn connects with upper diaphragm 20 which carries on its upper surface at the center diaphragm connecting lug 25, which in turn holds rubber shackle 26 in place. Lower diaphragm '19 is provided with a release valve Fig. 2, consisting of-diaphragm release valve ball'32 release valve housing 33Jand re- Very small intake phragm 19. An end shackle bracket 28 p rovides connection with rubber end'shackle-27 which in turn furnishesa pivot point for operating arm 29 on which operating weight 30 is slidably mounted and adjustable by set screw3l.

' v The whole mechanism is mounted in a convenient place under the hood of'the 'automobileat a'heightthat is above the highest oil'- 'i I 1gpoint of the, chassis. Assembly bolts 14 passed i line. The length of the strokeof the plungprovide adequate means for mounting the device to a bracket. Intake valve 5 is conveniently connected by means of intake pipe 37 to an oil feed tank located under the hood. Discharge pipes 46 are in turn connected with all the oiling points of the chassis. My oiling device shown in Fig. 1 is adapted to feed 24 oiling points but an increase in the length of the runway and a corresponding increase in the number of idlers vents and discharge pipes will meet the requirements of a bigger number of oiling points without increasing the size of the plunger.

Figures 4 and 5 show a variation of my oiling device without departing from the main principle involved. in place of using ball 'idlers 12 Figs. 1 to 3, disk idlers 39 are used which operate in idler grooves 40 Fig. 5, while key ball 11 runs in the original runway 7, The mode of operation is the same as that shown in Figures 1 to 3. Instead of using a diaphragm recoil mechanism as shown in Figures 1 to 3 I attain the same results by using the extension of the stuffing box nut 41 to forman expandibl'e air chamber with compression cylinder 42 and an valve consisting of housing33 ball 32 and springs 34. A series of weights 44 mounted on the wholepiston assembly take the place of lever and counterweight in Figures 1 to 3 and the action of this mechanism can be 'varied by adding to or removing weights 44.

"A retainer arm 43 fasten to the housing at its lower end and to retainer arm bracket 38 on counterweight 44 limits the upward motion of the plunger.

Before starting the oiling device for actual air vent 36 is opened and the whole oilwhole system is filled then plug is inserted and the air vent closed; 7

In operation my oiling device works as follows Right after the sion in the road and is on the rebound, operating weight 30 Fig. 1, still persists on the downward path, pushes down' the plunger 3 and expells the air from the diaphragm by means of the vent valve on the lower diaphragm 19. Plunger 3 will compress the oil providing a slight leakage in all the discharge vents by causing the oil to leak past the balls in the square cross section of runway 7 until the plunger hits an idler ball which in turn pushes the whol-e'row of balls ahead until'kcy ball 11 strikes one of the vent balls 9 thereby opening the discharge port of vent ball 9 to receivethe full charge-of oil displaced by the downward movement of the plungerand after the key ball has slid over the discharge port ball it comes to rest between the one and the next discharge port ball in ex depends on the force of the rebound and air vent automobile hits a deprestakes'place. Oil is sucked into the pump on this retarded stroke through intake 4 and valve 5. When key ball 11 is on the circular portion of runway 7 any backward movement of the key ball is stopped by the locking action of the different discharge port balls 9with key ball 11, see Fig. 3 dotted posi tion, but, just as soon as key ball 11 has reached the apex of the 'runwayand dropped into the vertical storage chute portion of runway? the idler balls 7 being smaller, would have a tendency to roll backdue to the in crease of weight on the left handof the runway of the idlers, and flow back towards the lunger. To prevent-such a condition idler brake ball 13 comes into action and prevents such an occurrence. After the key ball'ha-s dropped into the vertical portion of the runway 7 there will be one or two idler balls 12 ahead of'the key ball ready to receive-the impact of the plunger and as there'is no key ball in the circular portion of the runway all of thie'discharge balls 9 will lift slightly and provide a general leakageof oil in the oiling system until key ball 11is once more in operative position. Should the plunger hit one of the balls in such an unforeseen manner that it would jam between the sharp edge of the storage runway and the edge of the plunger, no damage canjocc 'ur'because on't-herebound theball is'released andpermittedtodrop into place after which the regular operation of the balls willresume. i

The use of 'rubber en'd shackle 27 and rubber shackle QG'eliminatesthenccessity of oiling the only movable parts of the oilingdevice not naturally bathed in oil during operation and they will also obviate wear and noise by the'use of this medium. If the automobile is regularly driven on rough gravel roads which would speed up theaction of the. oiler the oiling system can be adjusted by sliding the operating weight 30 Fig. 1, toward'the diaphragmand hold it in place by means of set screw 31, while on-continuous use onwell paved roads an increasedsensibility to shock can'be attained by reversing the adjusting'operation. Adjustment of the counter weight will be mainly dependent on the'consum'ption of oildesired on the basis 'of'experience and in anew stiff car the counterweightwill beset for increased oiling action while later on it willbeadjusted for more economic use of oil.

, Figures land's show a variation of my invention. wherein the motion of the idler.

disks 39 is confined within the limits of idler groove 40 so that none of the idlers have an opportunity of touching any of the discharge port balls 9. In this case also the retarding of the recoil motion is brought about by the slow seepage of air between extension of stuffing box 41 and compression cylinder 42.

My oiling device is subject to a variation of combinations and variation without detracting from the value of my invention.

A plurality of key balls can be used without changing the spirit of my invention. For instance a straight runway with a slightlyinclined return channel can be substituted for the semicircular course used in Fig. l to 5 inclusive which is shown in schematic drawing Fig. 6. This would avoid bunching of the oil lines and easier accessibility of the oiling device and-might lend itself to more restricted spaces. Figure 7 shows a schematic layout in a horizontally restricted space.

My oiling device lends itself as readily to the oiling of stationary machinery not subj ect to road shocks by the simpleexpedient of attaching a motion reducing rocker arm from any reciprocating part of an engine to the plunger, thereby limiting the stroke to apreconceived discharge capacity and a regular motion without detracting from the import of my invention.

It is also possible to derive the actuating motion of the plunger in automobiles from the chassis springs without materially changing the scope of my invention.
